| description | The invention relates to a finely divided, starch-containing aqueous polymer dispersion which is obtainable by free radical emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein the ethylenically unsaturated monomers comprise (a) from 30 to 65% by weight of acrylonitrile and/or methacrylonitrile, (b) from 35 to 60% by weight of at least one C1-C12-alkyl acrylate and/or at least one C1-C12-alkyl methacrylate, (c) from 0 to 35% by weight of at least one other ethylenically unsaturated copolymerisable monomer, in which the sum of (a), (b) and (c) totals 100%, and in which the aqueous polymer dispersion comprises, (d) from 10 to 55% by weight of an ionic tapioca starch, in which the weight of (d) is based on the total solids of components (a), (b), (c) and (d) of the aqueous polymer dispersion. The invention also relates to a process for the manufacture of the finely divided, starch containing aqueous polymer dispersions and also to the use of said finely divided starch containing aqueous polymer dispersions as a size for paper, board and cardboard.
L'invention concerne une dispersion polymère aqueuse finement divisée contenant de l'amidon qui peut être obtenue par polymérisation en émulsion radicalaire de monomères éthyléniquement insaturés en présence d'au moins un initiateur redox et d'amidon, les monomères éthyléniquement insaturés comprenant (a) de 30 à 65 % en poids d'acrylonitrile et/ou de méthacrylonitrile, (b) de 35 à 60 % en poids d'au moins un acrylate d'alkyle en C1-C12 et/ou d'au moins un méthacrylate d'alkyle en C1-C12, (c) de 0 à 35 % en poids d'au moins un autre monomère copolymérisable éthyléniquement insaturé, la somme de a), b) et c) étant de 100 %, et la dispersion polymère aqueuse comprenant (d) de 10 à 55 % en poids d'un amidon de tapioca ionique, le poids de (d) étant fondé sur les matières solides totales des composants a), b), c) et d) de la dispersion polymère aqueuse. L'invention concerne également un procédé pour la fabrication de dispersions polymères aqueuses contenant de l'amidon finement divisées et également l'utilisation desdites dispersions polymères aqueuses contenant de l'amidon finement divisées en tant qu'agent d'encollage pour papier, carton et bristol. |
